SAFE-DOOR- Specification of Letters Patent.

[\pnlicqtion filed February 6,1907. Serial NO- 356,110-

To all whom it may concern:

Be it known that I, l/VILL C. TTATTERSLEY,

a citizen of the United States, and residing at tached door.

held by means of a screw-connection. Fig. 2,

1 shows a central, vertical section of the de- Norwood, Hamilton county,State of Ohio, 5

have invented certain new and useful Improvements in the Construction ofSafe- Doors and I do declare the following to be a clear, full, andexact description of the invention, attention being called to theaccompanying drawing, with the reference characters marked thereon,which forms also a part of this specification.

This invention relates to improvements in the construction of doors forsafes of the kind where a circular, rotary door is held in place withina corresponding opening for it in the body of the safe, by closing meansconstituting a screw-connection and of the two complementary parts ofwhich connection one is provided on the door and the other within theopening for it in the safebody.

It relates further to such doors where the complementary part of thescrew-connection provided thereon is of a metal different from the metalof the door proper, as for instance in safes where this door is of anon-1nachinable metal, and for which reason the screwpart on it mustnecessarily be of a metal workable by tools in order to permit itsformation and construction.

The invention consists particularly of the means and manner whereby theclosing means provided for the d .r are connected to the body of thesame.

The invention is illustrated in connection. with a safe having acircular door which is made of non-machinable metal, like manganesecase-steel for instance and which is provided with the complementarypart of a screw-connection, which part is of workable metal.

In the following specification and particu larly pointed out in theclaims at the end thereof, is found a full description of my invention,together with its parts and manner of construction, which latter is alsoillustrated in the accompanying drawing, in which Figure 1, is aside-elevation of a safe-body partly in section, the line of sectionbeing taken through the door-opening therein, the door, appearing inedge-view, is shown in position within this opening in which it is Fig.3, illustrates that one of the complementary parts of thescrew-connection which is attached to the door and forms a constituentpart of the same, its side which comes against the door being shown.Fig. 4, is a side-view of this part shown in the preceding figure. Fig.5, is a perspective view of the door-body, showing that side of it whichreceives the screw-part shown in Figs. 3, and 4. Fig. 6, shows in acentral section both these parts placed together ready for finalconnection.

In the drawing 10, indicates the safe-body of conventional shape, thefront 11 of which is provided with the door-opening 12.

13, is the body of the door, assumed to be of non-machinable metal likemanganesesteel for instance. This door is held in place within opening12 provided for it, by means of a screw-connection comprising twocomplementary parts and of which one part, designated by 14, isconnected to door 13, in a manner that after such connection, whichremains permanent, it forms substantially 8 a constituent part thereof.This screw-part 14, being the male-screw of the screw-connection, isfitted to be received by the other complementary screw-part 15, whichcontains the female screw-thread and is provided 3 5 within door-opening12. The particular manner of providing this screw-part 15 is immaterialfor present purposes and does not concern this invention.

The manipulation and treatment for form- 9 ing and constructing parts 13and 14 which constitute the door, being different foreach, it becomesnecessary that each be produced separately, after which they are firmlyand permanently connected to each other, to form the door complete. Thisfinal connection of these two parts 13 and 14 to each other forms thesubstance of my invention.

Part 14, which contains the male-screw, consists substantially of acircular member or ring A, around the outside of which said screw isformed. On one of its flat sides and disposed at right angles thereto,there are a number of equally spaced projections 16, .all of equalextend and provided at their free I 5 ends with lugs 17 arranged atright angles to these projections from which they extend outwardly inradial directions. The doorbody 13 has a recess 18 on its inner sidewhich is of a depth sufficient to receive projections 16 onscrew-part A,and of a size diametrically, to admit also lugs 17 which extendlaterally from these projections. From the wall of this recess 18, thereproject inwardly, that is into it, lugs 19, corresponding in number tolugs 17 and spaced similar to these latter so that lugs 17 may pass inbetween these lugs 19. Part A, after having screw-thread 14 cut into itsouter side, is now placed in a position, with reference to door 13, asshown in Figs. 4, and 5, after which the two are brought together asshown in Fig. 6, so that the lugs on one pass in and through the spacesbetween the lugs of the other, af ter which part A, is given a limitedrotary shift, sufficient to cause lugs 17 on it to pass under lugs 19 inthe door-recess as'shown in Fig. 2, whereby these two parts, whichconstitute the door, become firmly interlocked. It is now only necessaryto provide means to hold. these two parts in such engaged position andto prevent them from turning one on the other in a manner which mightcause the interlocked lugs to become disengaged. For such purpose bolts21 are used,'which pass through openings 22 in part A, and enter tappedholes 23 in door-body 13. The drilling and tapping of these holes ismade possible by inserts 241, of soft, that is machinable metal andwhich are provided for during the casting of door-body 13. Anyinterstices between the engaged lugs may be closed and filled out bymolten metal 26 as shown in Fig. 2 applied through a suitable opening inmember A. This manner of connecting that part of the closing means of asafe, which is provided on the door, while illustrated as applied to around safe-door, and to one which isheld closed by means of ascrewconnection, is of course also applicable to doors held closed byother means, as for instance by a mutilated thread, or by interlocking,complementary lugs similar to those illustrated.

Having described my invention, I claim as new:

1. A door for a screw-door safe which has on its inner side a circularrecess and equally spaced lugs which project into this recess, a

screw-member which has spaced projections extending from its flat sidewhich have outwardly extending lugs at their ends and are adapted toenter the recess in the side of the door when door and screw-member areplaced against each other, the spaces between these projections beingsuch that the lugs which they carry on their ends are adapted to passthrough the spaces between the lugs in the door-recess and also underthem when one of the placed parts is rotatively shifted on the otherpart and means to hold the lugs in this position.

2. A door for a screw-door safe which has on its inner side a recess andspaced lugs which project into the same, a screw-memher which hasprojections on its side adapted to enter the recess in the doormentioned when placed against this latter, and outwardly projecting lugson these projections adapted to pass through the spaces between the lugsin the door-recess and also under them when one of the placed parts isrotatively shifted with reference to the other part, and bolts seated inthe screw-member and in the door to hold the lugs in the interlockingposition mentioned.

In testimony whereof, I hereunto aflix my signature in the presence oftwo witnesses.

It is hereby certified that in Letters Patent No. 855,706, granted June4, 1907 upon the application of Will 0. Hattersley, of Norwood, Ohio,for an improvement in Safe- Doors, an error appears in the printedspecification requiring correction, as follows: In line 39, page 1, thecompound word case-steel should read cast-steel; and that the saidLetters Patent should be read with this correction therein that the samemay conform to the record of the case in the Patent Office.
